Figure 2. Assessment of peptide and peptide spectral matches for identified proteins across brain regions.

Figure 2

(a) The frequency of unique peptides for all proteins identified from frontal cortex. More than 80% proteins identified with more than 2 unique peptides. (b) The frequency of peptide spectral matches (PSM) for all the proteins identified in frontal cortex. More than 75% proteins identified with more than 6 PSM, and about 85% proteins identified with more than 2 PSM. (c) The frequency of unique peptides for all proteins identified from the anterior cingulate gyrus. About 90% proteins identified with more than 2 unique peptides. (d) The frequency of PSMs for all the proteins identified in anterior cingulate gyrus. More than 85% proteins identified with more than 6 PSM. Both unique and shared peptide PSMs were considered in the analysis.
